RAZOR AND STROP Filed Jan. 2, 1952 5 INVENTOR I 1 Edwin 8. Olsen BY&': 2

l 7 ATTORNEY Patented Dec. 19, 1933 UNITED STATES PATENT OFFICE 2 Claims.

The invention relates to a razor and strop.

The principal object of the present invention is to provide a. razor and strop, so devised that when used in combination they will co-operate and function with one another to permit of stropping the blade of the razor, both sides. In this manner both the operation of sharpening the blade and the operation of shaving is greatly facilitated. 7

Referring to the drawing in which one embodiment of the invention is illustrated:

Fig. 1 is a perspective view of the razor in position for shaving;

Fig. 2 is asectional view, the handle portion being broken away;

Fig. 3 is an edge view in stropping position; and

Fig. 4 is a view taken at right angles .to Fig. 3, the strop being in section.

Referring again to said drawing the reference numeral 5 designates a U-shaped frame or yoke, having a handle portion 6 connected thereto. The yoke comprises arms 7 and a cross member 8.

Pivotally mounted in the arms 7 is a blade holder 9. The construction of the blade holder may be widely varied and as illustrated it consists of a single sheet of metal having opposed resilient blade-gripping wings 10 and an annular connecting portion 11. The blade 12, which may be a single or double edged blade, is clamped between the blade-gripping wings 10.

Means are provided for oscillating the blade holder and blade. Bearing studs 13 are secured in the annular portion 11 and extend through the arms '7. Fast on the outer ends of the studs are toothed members 14 which mesh other toothed members 15 mounted on studs 16 secured in the extremities of the arms 7. The toothed members 15 extend slightly beyond the extreme ends of the arms 7. Segmental members or friction rollers might be utilized instead of the toothed members 1414 and 1515.'

The strop 17, which is preferably rigid orsemi-rigid, has an elevated stropping surface 18 and longitudinal depressed side rails 19 adjacent the stropping surface. When the blade is being stropped, as illustrated in Fig. 3, the toothed members 15 engage the rolling surfaces or rails 19 and slide thereon imparting a gentle pressure to one cutting edge of the blade against the strop. During the stropping operation the razor is held by the handle 6 and the amount of pressure applied to the cutting edge of the blade may be eflectively controlled. When the end of a stroke is reached and the razor is moved in the opposite direction it will be apparent that the bladeoscillating mechanism will function to present the other cutting edge of the blade to the stropping surface.

It will be obvious from the'foregoing and the illustrations that the sharpening of the blade is made more effective by the minimum angle at which blade is engaged to sharpening surface which is made possible by reason of the depressed side rails and the elevated sharpening surface.

Means are provided for fixing the blade in position for shaving and this means may be varied. By way of example there is shown in the drawing a blade retainer 20, substantially semi-circular in cross section. Its inner end is sleeved at 21 and pivotally mounted on the cross member 8 of the yoke. Ears 22 are formed on the ends of the edge of the blade retainer remote from the pivot. When the blade occupies the shaving position, as illustrated in Figs. 1 and 2, the ears 22 take over the blade and retain it in its proper position. Intermediate the ears 22 the blade retainer is provided with guard teeth 23.

The blade retainer has a finger piece 24. When it is desired to sharpen the blade the finger piece is depressed and the retainer is moved to the position of Fig. 3 so as not to interfere with the oscillating movement of the blade and its holder. The sleeve 21 may embrace the cross member 8 with sufiicient friction to insure maintaining the blade retainer in either of its positions orother means may be provided for this purpose.

Numerous changes in details of construction and arrangements of parts may be made by one skilled in the art and the drawing is illustrative of only one embodiment of the invention expressed in the appended claims.

I claim: i

1. A safety razor having in combination, a

yoke and connected handle, a blade holder pivoted in the yoke, toothed members mounted on said blade holder outside of said yoke and other gears mounted on the extremities of said yoke and meshing said first mentioned gears, said second mentioned gears acting as rollers to engage depressed side rails of a strop so as to efiect periodic oscillation of the blade holder.

2. A safety razor having in combination, a

.yoke and connected handle, a blade holder piv-' oted in the yoke, toother members mounted on.

the extremities of said yoke, and means on the pivot of said blade holder cooperating with said toothed members so as to effect periodic oscilla tion of the blade holder when said toothed members acting as rollers engage depressed side rails of a strop.
